I remember being really angry all the time in my youth. And I valued that anger. I felt that I had been hurt so much, that the anger was something I could hold tight. That I kept that flame burning bright. I used it to keep the pain at bay. It wasn't healthy. Not at all. It distorted me and my perception. It only served to further isolate me. It takes a long time to change your mindset. Realize that being angry all the time is harmful to you. You're not hurting your parents with your anger so much as you are hurting yourself. Ask for help. Find a therapist to help you navigate your frustrations. I always felt isolated because of my stutter. In retrospect, my anger was likely more isolating than my stuttering. Regardless, because I felt isolated, I felt I had to do things on my own. That I could only count on me. That's a losing strategy. You're stronger when you are supported. Get support. Ask for help. Take the advice of someone who has spent their life learning to help others (not me... I mean a therapist.)
